How can I add "Repair Shop" to my Roku account?

Hi oldprog 

Thanks for the post.

Please be advised that Roku only rents and transmits the channel and is not responsible for the content. Contents are directly chosen by the respective channel and we have no control over the programming or operation of it. We would recommend contacting the channel directly for more information and assistance.

You can reach Discovery+ Support here. 

All the best,
Kariza

Something like this was posted before. The only guess is that Roku's search info is wrong. It might oddly be available if you get Discovery+ through the Roku Channel app, but possibly not.
